WebPotentiometric titration is the technique for determining the quantity of a specific test substance by adding titrant in small increments until the entire test substance reacts. The electromotive force, often known as the total potential difference, can be computed using the formula: Eind – Eref + Ej = Ecell WebA potentiometric surface is the imaginary plane where a given reservoir of fluid will "equalize out to" if allowed to flow. A potentiometric surface is based on hydraulic principles. For example, two connected storage tanks with one full and one empty will gradually fill/drain to the same level. This is because of atmospheric pressure and gravity.
